public float[] toRGB(float[] colorvalue)
This method transforms color values using algorithms designed
to produce the best perceptual match between input and output
colors. In order to do colorimetric conversion of color values,
you should use the toCIEXYZ
method of this color space to first convert from the input
color space to the CS_CIEXYZ color space, and then use the
fromCIEXYZ
method of the CS_sRGB color space to
convert from CS_CIEXYZ to the output color space.
See toCIEXYZ
and
fromCIEXYZ
for further information.

This method transforms color values using relative colorimetry,
as defined by the International Color Consortium standard. This
means that the XYZ values returned by this method are represented
relative to the D50 white point of the CS_CIEXYZ color space.
This representation is useful in a two-step color conversion
process in which colors are transformed from an input color
space to CS_CIEXYZ and then to an output color space. This
representation is not the same as the XYZ values that would
be measured from the given color value by a colorimeter.
A further transformation is necessary to compute the XYZ values
that would be measured using current CIE recommended practices.
See the toCIEXYZ
method of
ICC_ColorSpace
for further information.

This method transforms color values using relative colorimetry,
as defined by the International Color Consortium standard. This
means that the XYZ argument values taken by this method are represented
relative to the D50 white point of the CS_CIEXYZ color space.
This representation is useful in a two-step color conversion
process in which colors are transformed from an input color
space to CS_CIEXYZ and then to an output color space. The color
values returned by this method are not those that would produce
the XYZ value passed to the method when measured by a colorimeter.
If you have XYZ values corresponding to measurements made using
current CIE recommended practices, they must be converted to D50
relative values before being passed to this method.
